A text paragraph.

Required Associated Types

type Font: Copy + PartialEq

The font of this Paragraph.

Required Methods

fn with_text(text: Text<&str, Self::Font>) -> Self

Creates a new Paragraph laid out with the given Text.

fn with_spans<Link>( text: Text<&[Span<'_, Link, Self::Font>], Self::Font>, ) -> Self

Creates a new Paragraph laid out with the given Text.

fn resize(&mut self, new_bounds: Size)

Lays out the Paragraph with some new boundaries.

fn compare(&self, text: Text<(), Self::Font>) -> Difference

Compares the Paragraph with some desired Text and returns the Difference.

fn horizontal_alignment(&self) -> Horizontal

Returns the horizontal alignment of the Paragraph.

fn vertical_alignment(&self) -> Vertical

Returns the vertical alignment of the Paragraph.

fn min_bounds(&self) -> Size

Returns the minimum boundaries that can fit the contents of the Paragraph.

fn hit_test(&self, point: Point) -> Option<Hit>

Tests whether the provided point is within the boundaries of the Paragraph, returning information about the nearest character.

fn hit_span(&self, point: Point) -> Option<usize>

Tests whether the provided point is within the boundaries of a Span in the Paragraph, returning the index of the Span that was hit.

fn span_bounds(&self, index: usize) -> Vec<Rectangle>

Returns all bounds for the provided Span index of the Paragraph. A Span can have multiple bounds for each line it’s on.

fn grapheme_position(&self, line: usize, index: usize) -> Option<Point>

Returns the distance to the given grapheme index in the Paragraph.

Provided Methods

fn min_width(&self) -> f32

Returns the minimum width that can fit the contents of the Paragraph.

fn min_height(&self) -> f32

Returns the minimum height that can fit the contents of the Paragraph.

Object Safety

This trait is not object safe.
